Prevention of colorectal cancer through the endoscopic resection of pre-cancerous polyps is an important benefit of colonoscopy but is associated with a risk of serious adverse events, including bleeding. While immediate bleeding is usually managed at the time of the procedure, delayed post-polypectomy bleeding (after discharge from endoscopy unit, up to four weeks later) is […]

Endoscopic mucosal resection (EMR) uses adjunctive techniques to achieve curative resection of neoplastic lesions limited to the mucosal layers that are not amenable to cure using standard snare resection techniques alone.1 A flat, 3 centimeter, rectal lesion is well suited for EMR by initial injection of a submucosal fluid cushion, followed by confluent, wide-area, piecemeal […]

Treating large flat polyps in the rectum can be quite challenging for endoscopists. Among other things, the difficult location of rectal polyps such as ones in the lower rectum or near the rectosigmoid junction may affect endoscopic accessibility and stability, and limit snare maneuverability. One method of treatment, endoscopic mucosal resection (EMR) of polyps, is […]
